    "How Not to Invest" - with Barry Ritholtz

    Barry Ritholtz, founder and CIO of Ritholtz Wealth Management and host of the hit Bloomberg podcast Masters in Business, returns to Boxes and Lines to talk about his new book, How Not to Invest. Rather than presenting a traditional “how-to” manual, the book emphasizes what investors should not do, covering bad ideas, bad numbers, and bad behaviors. He joins Ronan and JR to break down everything from sketchy media advice to the famous bad trades of industry pros, why he believes market forecasts should be taken with a grain of salt, and why doing less might actually make you a better investor.

    Face to Face with Madoff: Diana B. Henriques on Interviewing a Conman and Watching De Niro Become Him (Episode 2)

    In Part 2 of our conversation with Diana B. Henriques, the Wizard of Lies author and veteran New York Times financial journalist takes us even deeper into the world of Bernie Madoff. She shares what it was like to sit across from him in prison, unraveling the psychology behind his massive Ponzi scheme and the ways he manipulated not just his victims but everyone around him. Diana’s book became the basis for the HBO film Wizard of Lies, starring Robert De Niro as Madoff. And in an unusual twist, she played herself in the movie. What was it like to act opposite De Niro, a method actor who studied Madoff’s mannerisms with almost obsessive precision? And did stepping into Hollywood change the way she saw the man she had investigated for years? Give it a listen!

    Bernie Madoff: The Trader, The Fraudster, The Legend (Part 1)

    Bernie Madoff was a market structure pioneer, a former NASDAQ chairman, and one of the most trusted names on Wall Street—bona fides that allowed him to architect the largest known Ponzi scheme in history under the noses of regulators. In this first episode of our two-part look at Madoff, Ronan and JR sit down with New York Times journalist Diana Henriques, author of The Wizard of Lies, which also inspired the HBO movie starring Robert De Niro. Diana, who was the first journalist to interview him in prison and played herself in the film, discusses Madoff’s early rise in electronic trading, the mechanics of his $65 billion Ponzi scheme, and how he kept finance’s biggest players on the hook for decades.

    Did DeepSeek Kill the Nvidia Star? - Boxes And Lines Lite

    It’s Boxes and Lines Lite, where we break down the biggest market stories in just 10–15 minutes. This time, we’re tackling the DeepSeek disruption—the surprise AI breakthrough out of China that sent Nvidia’s stock plunging, erased $600 billion in market value, and wiped nearly $100 billion from tech billionaires’ fortunes. Ronan and JR break down why markets reacted so dramatically, how DeepSeek’s low-cost, high-performance AI models are shaking up the industry, and whether this is just another dot-com-style overreaction or a real shift in the AI arms race.

    It's Gonna Be Weird: Dave Nadig on 2025 Predictions for the Market

    Dave Nadig, veteran ETF expert and self-styled “financial futurist,” returns to Boxes and Lines to look into his crystal ball and let Ronan and JR know what he sees in the cards for finance in 2025. First things first: It’s going to be a deeply weird year, Nadig predicts (there’s a reason why a telepathy podcast recently topped the charts over Joe Rogan). Beyond that, Nadig predicts we are about to enter a “corpostate,” batten down the hatches of “fortress America”  with tariffs galore and see the dawn of “Private Markets for Grandma.” He unpacked what all this means and more with the guys on our first episode of the year.
